Review Comment: Agreed. I think it's confusing and I don't find a right term yet. But, here is the [code line](https://github.com/apache/solr/blob/main/solr/core/src/java/org/apache/solr/handler/component/SearchHandler.java#L493) which is getting set by method [isDistrib(SolrQueryRequest req)](https://github.com/apache/solr/blob/main/solr/core/src/java/org/apache/solr/handler/component/SearchHandler.java#L307). Would you be able to help here with right term, may be `Standalone (AKA user managed)` as suggested? I am using `shards` param to query in my test case which uses `BaseDistributedSearchTestCase` (or I could have used distrib=true). > Your response didn't indicate if this would work for a SolrCloud single-shard collection. Will it? Yes, it would work for single shard or multi shard both. -- This is an automated message from the Apache Git Service.
